Debugging under JRuby in Rubymine 2.0 beta or lower
We're trying to debug jruby in rubymine, but receiving this error:
Cannot connect to the debugged process at port 55969 in 10s:
Error Output:
/Users/serguei/.rvm/jruby-1.4.0RC1/lib/ruby/site_ruby/1.8/rubygems.rb:827:in `report_activate_error': Could not find RubyGem ruby-debug-ide (>= 0) (Gem::LoadError)

from /Users/serguei/.rvm/gems/jruby/1.4.0RC1/bin/rdebug-ide:1:in `load'
from -e:1
even though gem list shows the following:
[jruby:1.4.0RC1] laptop:~ serguei$ jruby -S gem list | grep ruby
json-jruby (1.1.7)
ruby-debug (0.10.3)
ruby-debug-base (0.10.3.1)
ruby-debug-ide (0.4.9)
The file we're are debugging is very small and consists of:
require 'iconv'
require 'stringio'
non_utf8 = "\xa4"
puts non_utf8
utf8 = Iconv.conv('UTF-8//IGNORE', 'UTF-8', non_utf8)
puts utf8 == non_utf8 # returns true, which is wrong
Debugging on the command-line works, but not in Rubymine.
What is the right way to get debugging of jruby to work in RubyMine?

May be jruby points on other JRuby interpreter. Please invoke
Also which Language level do you use for your JRuby SDK in RubyMine (1.9 or 1.8) ?
$which jruby returns
/Users/pivotal/.rvm/jruby-1.4.0RC1/bin/jruby
In RubyMine the ruby language level is set to 1.8
I have the same problem with jruby debug not working under Rubymine, but I get a different error:
/Users/pivotal/.rvm/jruby-1.4.0RC1/lib/ruby/gems/1.8/gems/activesupport-2.2.2/lib/active_support/dependencies.rb:442:in `load_missing_constant': uninitialized constant Debugger::CommandProcessor (NameError)
I followed the instructions here to set up the jruby debugger:
http://kenai.com/projects/jruby/pages/UsingTheJRubyDebugger
I installed jruby via rvm on a new box and setup rubymine using instructions at
http://kenai.com/projects/jruby/pages/UsingTheJRubyDebugger
too. I'm now getting the same error as Chad

Debug works for me.
I'm on MacOS 10.6.1
0. I've downloaded JRuby 1.4.0RC1 from http://dist.codehaus.org/jruby/1.4.0RC1/
1. RubyMine 2.0 Beta
2. I created new sdk for JRuby 1.4.0RC1
3. Created project with file
4. Chose "Debug" from contex menu
5. RM suggested to install necessary debug gems. Then it showed progress dialog.
RM installed
6. Debugger started and stopped on breakpoint
Later I'll try rvm. But probably bug is in rvm gem.
Serguei,
Most likely problem is related to PATH env variable, see similar post related rvm - http://www.jetbrains.net/devnet/message/5246881#5246881
